Abstract: Mass heterogeneous and unstructured Web data makes it difficult to find necessary information.Using Web service technology,this article proposes a method of building metadata registry(MDR) and ontology management system(OMS) based on the semantics of metadata and ontology. By producding distributed closure, then implementing a search engine(SBWSE) using an ontology representing language RDF, it can help achieve high efficient access to distributed heterogeneous data, and settle the problem of incomplete and incorrect search results.

Key words: Web service , reasoning, ontology, metadata
